Pads 19 lofinssulating niate'iizil aie 201. At the opposite ends of the conductor bars 195, are located the similar insulating blocks 202 and 203 and adj acent to the middle portions of the bars 195 are located the similar insulating blocks 204 and 204.

'A pair of end hoisting and conveying trolleys each indicated in its entirety by the letter Gr are located at the ends of the shafts 177 and 185 which are each j ournaled in said end trolleys. Each of the trolleys G corn prises a housing with the vertical side walls 205 and 206 which are connected by the connecting members 207. Bosses 208 are formed with the walls 205 and 206 and which have extending therefrom pins 209 that have journaled thereon the rollers 210. The shaft 177 has fastened thereto the pinions 211 that mesh with the rack 164. A hoisting drum 212 is'fastened to the shaft 185. A hoisting rope 213 has 'one end fastened to thedrum 212. A shaft 216 is journaled in all the trolleys and has fastened thereto adjacent to the trolleys G the sheaves 217. Adjusting ropes 218 extend over the sheaves 217.

Intermediate hoisting trolleys designated in their entirety by the letter H. each comprises the housing consisting of the vertical walls 221 that are connected by the connect.

ing members 222. Bosses 223 extend from the inner faces of the walls 221 and carry the journal pins 224. Rollers 220 arejournalecl on the pins 224. All the shafts 17 185 and 216 are journaled in the vertical walls 221 of the trolleys H and extend through the same. A hoisting drum 225 is located between the vertical walls of each trolley H and fastened to the shaft 185. A hoisting rope226 has one end fastened to each of the drums 225. On the opposite ends of some of the trolleys H are supported spring bumpers.

The bumpers comprise lugs 227 which are cast with the connecting members 222. Bolts releasing bar 254 lowers. The motor 182 is 228 with the heads 229 are supported in openings in the connecting members 222 and lugs 227. Springs 229 aresupported on the bolts 228 between the lugs 227 and the heads 229. Nuts 230 are in threadedengagement with the bolts 228.

The bumpers contact with the girders 31 when the trolleys accidentally run tothe sides of the ice house 20. Connecting bars 234 connect the different trolleys. The hoisting-ropes187, 213and 226 at their lower ends are connected to the hoisting bar 230. Chains 231 connect the hoisting bar 230 and the pairs of chains 232.

Chains with the members 250 and 251 extend from the opposite ends of the'bars 245 and are connected to the ropes 218;} Journal brackets 252 extend from the girders 31 and have journaled therein the guide sheaves 253. The ropes 218 extend over the guide sheaves'253 and are fastened to the releasing bar 254. A releasing rope 255 has one end fastened to the connecting bar 254. A reversing switch 256 with the operating chain 257 is secured to the wall 25, and coacts with the hoisting motor 182. A reversing switch 258 with the hand chain 259 and coacting with the conveyer motor 176 is secured to the wall 25. 1 A pair of main line wires 260, 261 lead from a source of electricity 263 and have connected thereto the branch wires 264, 265 for the reversing switch 256,'andthe branch wires 266, 267 lead from said main line wires to the reversing switch 258. Wires 270, 271 connect the switch 256 with the conductor bars 195 and wires 272, 273 connect the reversing switch 258 withthe conductor bars 193. Y

To operate the apparatus, themain hoist ing and conveying trolley F is located to bring the ice tongs I over the cakes of ice J tov be handled. The operator next pulls'the disengaging rope 255 so that the lower membore 236 of the tongs will straddle the cakes J. When the rope 255 is released the pins 238 will engage the side faces of the cakes J.

The operator now pulls the'hand chain 257 of the switch 256 to start hoisting motor 182 in its hoisting direction and the hoisting drums 186. 2l2and 225 turn, and the hoisting bar 230 rises with the tongs-I and the cakes of ice J. At the same time the hand chain 259 and reversing switch 258.

By means of the. trolleyswith the tongs I, the cakes J of ice are moved as desired. The

chain 257 is now-pulled to reverse the rota tions in hoisting motor 182 and the cakes of ice J are lowered in place. The operator next. releases the lower members 236 ofthe Cal Cfi

, and the insulating blocks198 and 203 in "19 a similar'manner prevent the trolleyscontacting with the wall of said building \Vhen the apparatus is used to transport ice toward the side 24 of the building 20, the

insulating blocks 200 and 204 are removed, and conductor bars are substituted in their places and the insulating blocks 201 and 204 prevent the apparatus from running "beyond the center oft-he building. In case the apparatus is used between the center of the building and the wall 25, the insulating blocks 201 and 204 are removed and'conductor bars substituted; By this means the trolleys are preventedfrom running beyond substituted in their places; 7

the central portion ofthe building In case the cakes of ice are to be moved from one side of the building and conveyed to the other side of'the buildingall the intermediate insulatingb locks 200, 201, 204 and 204 are removed and conductor blocks By means of'the "sprocket chain wheel 179 and chain 180 the trolleys F, G and II may be manually moved on their supporting I- beams 163 and by means of the sprocket chain wheel '188 and hand chain 189' the hoisting chains of said trolleys maybe raised or lowered.

In the modification represented in Fig. 1 tongs M are substituted fon the tongs I and a plurality of these tongs are used simultaneously as idescribed'for the tongs I. The tongs M each comprise aws with the members 235, 236, gripping pads 237 with the gripping pins 238, eyelets 240 on one of each member 236, with theconnecting bar 245 and pins 246 as already described. The other members 236 of each pair of jaws are rigidly connected by the connecting bar 247. Chains 232 connect the members 235 and chains 231 connect the chains 232 with the hoisting bar 230, Hoisting ropes 187 extend from the bar 230. Adjusting ropes 218 are connected to the chains 251 which in turn are connected to the bar 245.

The operation of this modification. is similar to that described for the'tongs I, with the exception that only one of each pair of jaws is raised by the rope 218 and its appurtenances when the tongs are opened, to release the cakes of ice.

It will be noted that the connecting bars 245 are smaller in diameter than the inside diameters of the eyelets 240, by virtue of which sufiicient clearance space is provided between said connecting bars and eyelets to insure the and M. 7

When the cakes of ice vary in width and the tongs I or M are lowered in place, the operator pulls the releasing rope 255 to spread the lower members236 of the tongs to clear all the cakes of ice. When the rope 255' is subsequently released the gripping 7 pins 238'will all engage their accompanymg cakes of ice, by reason of the clearancebe tween the eyelets 240 and the connecting bars 245. Y
